HENRY C. ROLLER, OF NEWARK, NEW JERSEY.

LUBRICATOR.'

SPECIFICATION forming part of Letters Patent No. 499,595, dated June 13,1893.

Application filed January 26, 1893. Serial No. 459,861. (No model.)

To all whom it may concern.-

Be it known that I, HENRY O. ROLLER, of Newark, in the county of Essexand State of New Jersey, have invented a new and Improved Lubricator, ofwhich the following is a full, clear, and exact description.

The invention relates to sight feed lubricators, and its object is toprovide a new and improved lubricator, which is simple and durable inconstruction, very eifective in operation and arranged for properlyfeeding any grade or quality of oil in either an up or down direction.

The invention consists of an oil supply tank adapted to contain the oilto be fed under boiler pressure, the said tank being connected with thesight feed tube.

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafter described and thenpointed out in the claim.

Reference is tobe had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts in section.Fig. 2 is a sectional plan view of the same on the line 2-2 of Fig. 1.Fig. 3 is a side elevation of the improvement with parts in section andshowing the oil supply pipe passing through the steam pipe for heatingthe oil. Fig. 4 is a sectional plan view of the same on the line 44: ofFig. 3; and Fig. 5 is a side elevation of the improvement with parts insection and arranged for down feed.

The oil tank A is connected by a pipe B with the boiler, so that the oilcontain ed in the said tank Awill be in contact with the steam, and, toa certain extent, under the influence of boiler presure. From this tankA leads an oil supply pipe 0 to convey the oil to the respective part tobe lubricated in the manner hereinafter fully set forth.

The pipe 0 may be passed through the steam pipe D into which thelubricant is to be discharged, so that the oil is heated, previous toentering the steam pipe. The pipe 0 connects with a casing E supportedfrom the steam pipe D, and containing a valve F for controlling theamount of lubricant passing from the pipe 0 to the casing E. The latterconnects with the sight feed tube G also connected with a second casingH discharging into the steam pipe D to be lubricated.

In the casing H is arranged a valve I for controlling the amount of oiland steam passing through the casing H to the pipe D. On top of thecasing H is arranged a steam condensing chamber J in which part of thesteam can condense to fill the tube G with water of condensation. A dripcock K is arranged on the under side of the casing E and serves to cleanthe sight feed tube G, the said drip cock being opened forthispurpose,so thatthesteam will pass downward through the casing H, thesight feed tube G and out of the drip cock K. When this is done, thevalve F is closed to shut off the oil supply. I

As illustrated in Figs. land 3, the feeding of the oil is in an upwarddirection and in this case the casing E is below the casing H, but if itis desired to feed the oil in a downward direction then the positions ofthe easings are reversed, as illustrated in Fig. 5, and the condensingchamber J is omitted. Now, it will be seen that the oil from the tank Ais forced into the casing E by the displacement due to the condensationof steam and also,

partially, by the pressure of steam, so that the oil rises in drops inthe sight feed tube G to finally pass through the casing H and past thevalve I into the pipe to convey the lubricant. In the down feed theoperation is similar, with the only difference that the oil entering thetop casing E under boiler pressure is forced downward through the sightfeed tube G to finally pass through the casing H into the steam pipe D.

It will be seen that the casings E and H can beplaced any desireddistance apart, so as to provide for any desired length of sight feedtube G.

It will further be seen that as the lubricant is under the heavy boilerpressure, any grade "of oil can readily be fed, as the oil is forcedwith considerable pressure through the apparatus Without blocking thesame, to finally pass into the steam pipe. I

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent ICC) Alubricator, comprising an oil supplytank, a steam-pipe leading thereto from the boiler, sight feed tubes,supply pipes connecting the said tank and the sight feed tubes, casingslocated at the ends of the sight feed tubes and connected the one withan oil supply pipe and the other with the corresponding lubricantconveying steam-pipe, an oil regulating valve arranged in the casingconnected with the 10 oil supply pipe, a steam valve arranged in theother casing, and steam pipes for conveying the oil from the sight feedtube to the parts to be lubricated, the said oil supply pipes beingpassed through the lubricant conveying steam-pipes, substantially as de-15 scribed.
